This invention relates to a machine or apparatus for washing dishes, silver and the like and more particularly to a machine of the class described which may be operated by hand and which may be produced at a cost which renders it practical for individual homes.

It is an object of this invention to provide a machine of the class described which will exert a thorough and rapid cleansing action on soiled dishes, silver, etc., whereby the same may be rapidly and easily cleaned with a minimum of exertion.

It is a further object of this invention. to provide a machine of the class described having improved means for producing flow of water against all sides of the dishes being washed and furthermore to provide a machine of the class described in which the space within the body and cover of the machine is utilized to the greatest possible extent.

It is a further object of the invention to produce an improved method of circulating the cleaning fluid in and around the dishes to be cleaned to exert a thorough and rapid cleaning action in a minimum of time.

It is still a further object'of the invention to provide improved means for positioning dishes and silverware to be cleaned within the machine and for maintaining them in position during the-cleaning action of the machine to prevent movementof the dishes and accidental breakage thereof.

provide a machine of the class described which-miay be easily and quickly drained of fluid (contained therein after washing a charge of dishes, and which may be disassembled to permit of a thorough cleaning of the machine with a minimum of time and labor.

Still other objects will be apparent from the specifications.

The features of novelty which I believe to be characteristic of my invention are pointed out with particularity in the appended claims. My invention itself however, both as to its underlying principles and as to its .practical application will best be understood It is a further object of the invention to by reference to the specification and accompanying drawing in which:

Figure 1. is a longitudinal and sectional view through the machine according to my invention, on lines 11 of Figure 2.

Figure 2 is a plan view of the complete machine according to my invention showing the portion of the cover or top broken away. Figure 3 is an exploded assembly'view showing a front elevation of the various parts. i

Figure 4 is a transverse section on lines 4-4 of Figure 1.

Figure 5 is a top plan view of the adjustable dish rack.

Figure 6 is a perspective view of the cup or silver tray and cover.

- Figures 7, 8 and 9 are diagrammatic views explaining the operation of my machine.

Figure 10 is a perspective view of the water deflector removed from the machine and showing the valve mechanism.

' the body may be rocked. An adjustable dish rack is provided and. preferably arranged so that it may be mounted therein and when so mounted its top and the top of the-dishes carried therein will not project above the body of the machine.

Also I provide a relatively deep top or recessed cover member for the machine which may be clamped in place to make a substantially water tight machine which may bev rocked without causing fluid to leak out therefrom. Within the cover I provide one or more water deflecting surfaces such as a flat plate having one or more valves therein which will permit water to pass through in one direction and not in the other and so arranged that when the machine is filled with fluid and rocked, in one direction, a certain place cups,

faces.

For convenience in draining the machine I provide a swingable spout or'hollow arm attached to one side of the machine at substantially the bottom thereof and I also preferably provide a false bottom within the machine arranged so that the fluid will flow by gravity from all parts of the machine to the discharge spout when the machine is in its normal position.

Referring now more particularly to Figure 1, 1 designates generically the body of the machine or receptacle and 2 the cover thereof. The body 1 is formed with preferably parallel flat sides 3and 4 and bottom 5 which is shaped on a curve to permit rocking of the machine. An opening 6 .is formed in the side 4 of the machine and preferably at the bottom thereof and on thezouter side of this opening there may be attached as for example by suitable bolts, rivets or the like a hollow sleeve 7 to which is rot'atably or swingably secured spout 8 having a suitable packing .9 therein to prevent leakage. If desired an additional spout 10 may be provided telescoping within spout 8, by which the eflective length of the draining spout. may be adjusted as desired.

In' order that the machine may be easily drained a false bottom 11 may be provided so that fluid in the machine will flow from all parts thereof to the drain spout by the action of gravity when the machine is in its normal position.

In order to securely hold the dishes to be washed in proper position and to avoid undesired movement and breakage of the same. I provide a dish rack 12 which is preferably made up of a lower pair of spaced longitudinally extending members 13 and 14 and a second or upper pair of longitudinally extending members 15 and 16 vertically spaced from the members 13 and 14. In order to maintain the dishes in position I provide U- shaped arms 17 18, 19, 20, 21 and 22 having each a base portion 23 and two side portions '24 and 25. The side portions 24 are attached at their upper ends to the longitudinal member 15 and near the base to the longitudinal member 13 while the arms 25 are similarly attached to longitudinal members 16 and 14. The attachment of these various members is best-made. by bolts and wing nuts 27 and 28 respectively and the longitudinal members. say, are provided with slots 29 to permit of adjustment of the support to accommodate the various sizes of dishes.

In order to support the tops of the various dishes there are provided a plurality of L- shaped arms 30 having one end secured in the bottom members 23 of the U-shaped arms 17, 18, 19, 20, 21 and 22. The opposite ends of the L-shaped arms 30 are extended inwardly at right angles to the upstanding portion and passed into sleeves 31 thus providing supports which may be adjusted to support all sizes of dishes both at the bottom .and at the top.

In order to support the dish rack with its dishes out of contact with the bottom of the machine there may be provided end portions 33 adapted to reston the bottom 5 of the body of the machine, which also act as braces to strengthen the dish rack.-

Referring now to the cover 2, this is formed of a shape to correspond with the body of the machine and has sides 35 and 36, ends 37 and top 39. On the inside of the side 36 there is provided a rib 40- and a second rib 41 vertically spaced therefrom. Similar ribs 42 and 43 are provided on the side 35 and at the oppositev end on side 36 there is provided rib 44 and rib 45 similar to ribs 40 and 41 and likewise on side 35 opposite to ribs 44 and 45 another set of ribs. not shown. The ribs 40 and 41 are adapted to support one side of a water trapping plate 46, and the ribs 42 and 43 .the other side thereof, as will be seen from Figures 1 and 4. The water trapping plate 46 is provided with an opening 48 therein which opening is normally closed by a plate 49 mounted on hinge 50 over the opening 48 so that plate 49 is freely swin gable away from plate 46. A similar construction may be provided on the opposite side of the transverse median plane of the machine where plate 47 is shown having opening 48 normally closed by valve 51. The function of the plates and valves will best be understood by reference to, Figures 7. 8 and 9 which show a simplified diagram of the operation and circulation of fluid in the machine without reference to dishes contained therein. After the machine is substantially filled with fluid 52 the nor-.

mal position of the valves and'also of the fluid will be that shown in Figure 7. If however. the machine is rocked or tilted to the position shown in Figure 8 the fluid 52 passes through the opening inplate 46 and presses against valve 49 lifting the same from its seat and flowing above plate 46. If now the machine is tilted to the position shown in Figure 9 the pressure of fluid 51 trapped above plate 46 will cause valve 49 to close and prevent the flow of water therethrough. The fluid therefore flows out over the edge of the plate 46'and dowhwardly on top of the dishes thereunder. Further tilting of the machine in thedirection shown in Figure 9 will cause flow of fluid through valve 51 and when the machine is returned to the position of Figure 8 a similar action takes place, the fluid being loo . rection against the dishes to be cleaned, but

. wardly upon them at different angles. The result of this is that the most tenaciously adalso subjects them alternately to deluges of cleaning fluid falling laterally and downhering grease, dirt and the like are quickly and easily loosened and removed, and the effectiveness of the cleansing action of the machine greatly'enhanced.

In order to provide for washing cups and other small articles and utensils such as silverware there may be provided a plurality of trays formed of-suitable wire mesh and having one or more compartments as desired. A reinforcing member or band such as metal strip 56'is preferably provided extending around the top of the basket or tray which strip is provided withsuitable holes 57, in its front side and other holes not shown in its back side. A cover .59 is provided adapted to fit within and upon the tray and having end portions in the form of sleeves and 61 engageable by pins 62 and .63 which may be passed through holes 57 and 58 then through sleeves 60 and 61 and finally into the holes not shown in the back of the tray thereby securely holding the cover in place upon the basket or tray.

The interior of the cover is provided with 211163.118 for mounting the trays comprising suitable ledges 64 extending inwardly from the cover and suitable hook members 65 turnably mounted on or attached to the cover. In order to mount the trays 55 in position the machine cover 2 may be turned on end or on its side, the hooks 65 turned outwardly, the

' tray inverted and placed therein 'so that one end rests on ledges-64, and the member 65 turned inward until its hooked end rests under and supports the opposite end of the inverted basket or tray 55.

Suitable means are provided for making a water tight connection between the cover and the body of the machine, as for example, flange 66 attached to the body portion and having a depression in which may beplaced a suitable gasket 67. The cover maythen be provided with a member 68 adapted to be clamped upon the gasket 67 and suitable latching means, such as snap latches 70 may be provided on opposite sides and at the ends of the body or cover as desired.

From what.- has already been said it isthought that the operation of the apparatus will now be readily understoodf The dishes,

may be placed as indicated in dotted lines in Figure l-in the dish rack, the cups or silver,

etc., in the trays, the tray cover fastened in place and the trays inverted and mounted within the machine cover. as already described and finally the machine may be filled with hot water to which have been addedthe desired cleaning agents after which the cover will be securely fastened in position by the fastening latches. If now the machine be given a rocking motion as shown in Figures 7, 8 and 9 a relatively short time will suflice to thoroughly clean the dishes contained within it since by rocking the machine the water is thoroughly agitated and forcibly thrown against the dishes from all sides. In order to drain the liquid from the machine itis' only necessary to swing the discharge pipe 8 as indicated .in Figure 3 after which the fluid will flow out through the drain pipe. The drain pipejmay now be returned to its original position and the machine again filled with water in order to rinse the dishes.

It should be pointed out at this time that in order to clean the machine after use the dish rack may be bodily removed from the machine to expose all surfaces for cleaning or inspection and likewise the water deflecting plates 46 and 47 may he slid out so as to expose all surfaces and prevent the accumulationof any dirt in places difficultto reach. For convenience in mounting the plates 46 and 47 between the supporting ribs, the ends of the ribs may be bevelled as shown in Figure 1.

In Figures 11 and 12 Ihave shown a modified form of discharge mechanism comprising stopper 72 mounted to' cover hole 71 in the bottom of the machine and pivotally carried on lever 73 pivoted at 74 and biased to closed positionby spring 75. In this instance when it is desired to drain the machine the outer end of lever 73 will be depressed thereby withdrawing stopper 7 2 from hole 71. In this case it will'be seen that it is necessary to provide rails or rocking surfaces 76 and 77 upon which the machine may be roekably supported.

While I have shown and described certain preferred embodiments of my invention it is to be understood that modifications and changes may be made as will be apparent to those skilled in the art without departing from the spirit and scope of my invention.-
